Support for multiple VideoCall.Listeners for a VideoCall.

Browse Source 
The current code assumes that only a single instance of VideoCall will be
provided to the default system InCall UI.  Ideally multiple
InCallService implementations should be able to use the VideoCall APIs.
Note: it only really makes sense for a single InCallService to get/set
the video surfaces.

- Fixed bug in ParcelableCall which would cause a new instance of
VideoCallImpl to be created every time a call is updated from Telecom.
Added a flag to ParcelableCall to indicate whether the parcel includes a
change to the video provider information, which is used when unparceling
to determine whether to set/create the video call impl.
- Renamed "setVideoCallback" to "addVideocallback".
- Modified Connection.VideoProvider code to keep a list of Video callbacks
and fire off all of them when Video Provider changes occur.
